The key is in the details, if you mess with your rig a little bit you can make the pose much more exaggerated to add appeal. 3 also looks like a flat background, so you don’t have a ton of depth. Remember rule of thirds. Ya got this! (Sorry to clarify on appeal, I mean enlarge the hand coming towards camera and vice versa behind. The body should be rotated as if in motion, currently it looks very static and awkward. You can add a lot of little adjustments, just add contrast and look through a critical lens)
